------- Comment #7 from Murray Cumming  2006-02-22 08:16 UTC -------
You probably don't want to hear this right now, but I just remembered tha=
t this
has missed the API freeze for GNOME 2.14, so it could only be released in=
 a
stable version of glibmm in about 6 months's time. I'll branch glibmm soo=
n
after GNOME 2.14, so I can commit this. In theory, we can ask for a
freeze-break but I  don't think that's a good idea, because we wouldn't h=
ave
enough time to get feedback on the new API.

(GNOME 2.14 will have glibmm (and glib) 2.10 and gtkmm (and GTK+) 2.8.)

I'll investigate the "Value is not a template" issue at that time.

Many thanks and well done.

I've added a list_icons() method overload in cvs HEAD (for gtkmm 2.10), a=

corrected the documentation. For now, you can use the C API (with all the
GList* and g_free fun), which allows you to specify a NULL gchar*. Thanks=

(To add  another comment, the fact that the pixel for your display was
close enough to a RGBA value to just shift is entirely coincidental ...
if you had a 16 bit display you'd have to extract out and shift around
subfields, and it gets worse from there. You really want to form the
value passed to gdk_pixbuf_fill() from the RGB fields of the color,
not the pixel.)

[Like I said, I don't really understand the concept of what a 'pixel' is
supposed to represent]

Just to clarify, you're saying that the pixel field of GdkColor is depend=
ent on
my display, but the pixel argument for gdk_pixbuf_fill is not?  These are=
 two
different concepts? =20

Could you give a brief layman's overview of what pixel means in these two=
 cases
are so that I can add something to the documentation?

------- Comment #7 from Owen Taylor  2006-02-22 15:41 UTC -------
gdk_pixbuf_fill() is documented in the C documentation. The pixel in
GdkColor is just the value that will be stored into display memory,
more or less. (Usually, nowdays, things in GTK+ use *unallocated* colors,
which means that the pixel field is just left as zero.) Also see the
C docs for GdkColro.

------- Comment #8 from jonner  2006-02-22 16:51 UTC -------
I have looked at the C documentation for these functions, but unfortunate=
ly it
didn't really tell me much.  Yes, the gdk_pixbuf_fill() argument is descr=
ibed
decently in the documentation, but the fact that it's named 'pixel' and i=
s the
same type (guint32) led me initially (and wrongly) to believe that it was
analogous to the pixel concept in GdkColor.

For GdkColor, the closest the API documentation gets to describing a pixe=
l that
I could find is the following:

guint32 pixel;  For allocated colors, the value used to draw this color o=
n the
screen.

This tells me almost nothing and merely begs a lot of questions in my min=
d.=20
Now that I dig into the source a bit more though, I found this comment in
gdkcolor.h, which I can't find in the API documentation anywhere (and pos=
sibly
should be added, since it clears up a few questions for me):

/* The color type.
 *   A color consists of red, green and blue values in the
 *    range 0-65535 and a pixel value. The pixel value is highly
 *    dependent on the depth and colormap which this color will
 *    be used to draw into. Therefore, sharing colors between
 *    colormaps is a bad idea.
 */
struct _GdkColor
{
...
};


So am I right in concluding that a pixel value is not useful outside of
GdkColor- and GdkColormap-related functions?  Or are there other places t=
his
value could be used?

Also, does pixel have a particular format, or is it supposed to be treate=
d as
an opaque type that shouldn't be examined by the application?

I apologize for taking up so much of your time on such a seemingly simple
misunderstanding, but colormaps and allocating colors is one of those thi=
ngs
that baffled me when I started learning gtk, and it seems I still don't h=
ave a
good handle on it.

get_pixel() is implemented like so:

guint Color::get_pixel() const
{
  return gobject_->pixel;
}

_If_ GdkCOlor::pixel is private and useless then we should deprecate this
method. I have no idea - it's before my time.

------- Comment #10 from Owen Taylor  2006-02-22 17:11 UTC -------
Well, the pixel value is interpretable using values you can return
from GdkVisual ... it's has a defined structure and isn't opaque
in that sense. And you might want it if you were manipulating screen=20
data directly with GdkImage. But it's not useful for most uses of
GdkColor these days.

If  you really want to understand the details of visuals, colormaps,
pixel values and so forth, please look at the documentation for X.
(Most Linux distributions provide it in Postscript form, possibly as an
optional package.)
